KITCHEN-RANGE.

Specificationof Letters Patent No. 4,599, dated June 20', 1846.

deceased, did jointly invent certain new and.

useful Improvements in the Manner of Constructing Kitchen-Ranges, theright to which it was our intention to secure byLetters Patent and whichintention it is the object of this instrument of writing to consummatefor my benefit and for the benefit of the heirs at law of the saidALEXANDER S. WALOOTT, deceased; and I do hereby declare that thefollowing is a full and exact description of the said improvedkitchen-range.

This range when made with a single oven as herein described andrepresented has-on one side of it a grate or fire chamber for containingthe fuel and an ash-pit beneath it formed in the usual manner; and onits opposite side there is an oven with a flue space above and below it,which two flue spaces communicate with each other by means of a lateralflue space extending from front to back of the range on that side of theoven which is farthest from the fire chamber, said flue being formed byone of the amb plates and a side oven plate. I will here remark howeverthat we had it in contemplation sometimes to make our range with twoovens, the fire chamber being placed between them, but in this case theprinciple of construction would not be changed, the additional ovenbeing combined with the fire chamber in a manner precisely the same withthat herein described.

Behind the fire chamber there is a descending flue which extends downbelow the bottom of the oven, and opens into the flue space formed bysaid oven bottom and the bottom plate of the range. This descending fluespace is lined with soap-stone, fireclay, or any other bad conductor ofheat in order to prevent the loss thereof. The heated air from the firedescends through said lined flue space, then under the oven, and up thelateral flue space,tl 1ence over the oven to the exit or smoke plpe.

To cause the draft to pass directly downthe rear flue space, and aroundthe oven as described, there is a partition extending across the upperflue space, and dividing it from the fire chamber so as to include theexit pipe in said flue space; but there is an opening in this partitionwhich is furnished with a valve or shutter which, when open,

will allow the heated air from the fire chamber to pass thence to theexit pipe without passing down the rear flue but this valve or shutteris so situated, and the respective openings in the top plate soarranged, as to cause the heated air in its passage to act aseffectually on the cooking utensils which are immediately over the ovenplate, as when it is conducted down the rear flue and around the oven.There is a sliding damper also so arranged as to close the lateral flueat its upper part, when the oven is not to be used and the heated air isto pass directly to the exit pipe. The form given to the range is suchas to adapt itto the sloping jambs of a fire place, and this formfacilitates the bringing of the heated air into contact with the bottomsof the cooking utensils as above named. On the upper side of that partof the bottom plate of the range which is immediately below the bottomplate of the oven, there are cast a number of points or projectingridges which may rise to the height of an inch more or less; the asheswhich lodge between these will constitute an excellent nonconductinglining to this part and contribute greatly to the efliciency of the ovenand will be retained there when the superfluous portion is removed by ashovel.

In the accompanying drawing Figure 1' is a perspective view of theimproved range. Fig. 2 is a top view thereof with the top plate removedand Fig. 3 is a view of the inside of the bottom plate.

A is the top plate with its boiler openings and the exit or smoke pipeB; two of the boiler openings a and Z) are into the flue space above theoven and the others 0 (Z and e are over the fire chamber C. Theseopenings are furnished with lift-outs of the ordinary kind, so that theymay be enlarged if required. n

D is the oven door which is sometimes made to slide in grooves, but itmay be hung as a drop door, or otherwise.

is the handle of a sliding valve which is made to close or regulate theopening of the lateral flue space, as shown distinctly in Fig. 2; inthis figure E E is the top oven plate, and F F a partition extendingfrom this plate to the top plate A, so as to divide the compartmentcontaining the fire chamber C from that containing the boiler opening aand b, In the fore part of the partition F there is a valve or shutterGr by which a communication may be established between the twocompartments; and by the situation of this valve, and'the jamb like formgiven to the ends of the range, the heated air from the fire chamberwill, on its way therefrom to the exit pipe, act with its whole power onthe cooking utensils in the compartment over the oven.

H is the sliding valve that is made to close the lateral flue space I.The triangular opening J immediately behind the fire chamber is thedescending flue which communicates with the flue space immediately underthe oven; which flue space has a lining g of soap stone, &c. to preventthe loss of heat. The fire chamber also is similarly lined.

In the inside view of the bottom plate of the oven shown in Fig. 3, h,h, h are the projecting ridges to detain a lining of ashes under theoven; 2' i is the place of a partition plate extending up to the bottomplate of the oven, so as effectually to distribute the heated air whichpasses under the oven on its way to the lateral flue space. The form ofthe fire chamber, of the descending flue, and of the oven in horizontalsection, are distinctly represented in this figure.

Having thus fully described the manner of constructing and arranging therespective parts of the improved kitchen range, what is claimed as newtherein and desired to be secured by Letters Patent is The particularmanner of arranging and combining the fire chamber, the descending fluein the rear thereof, duly lined as described, and the flue space underthe oven so that the heated air shall operate first on the bottom plateof the oven; also themanner of arranging the partition F F and the valveor shutter G so as to compel the heated air, whenallowed to pass fromthe fire chamber to the exit pipe, to operate with its full intensity onthe cooking utensils that are placed in the compartment over the oven,and likewise the employment of ridges or points on that part of thebottom plate of the range that'is immediately under the bottom ovenplate, in the manner and for the purpose herein set forth.
